I have a web-based PHP email client (Roundcube) that I installed on a UNIX server, and right off the bat it produced this error:

Fatal error: Undefined class constant 'MYSQL_ATTR_FOUND_ROWS' in /path/to/file.php on line 134

It's this line of code:

$result[PDO::MYSQL_ATTR_FOUND_ROWS] = true;

Locally on my Windows installation it works fine, so I compared the two PDO classes with this:

<?php ReflectionClass::export('PDO');

The MYSQL_ATTR_FOUND_ROWS property and some others weren't present on the live UNIX server. I did a quick patch by hardcoding the unknown value and it worked great, but I can't be sure there aren't more bugs (and we don't want to use a hacked version anyways).

The PDO class is definitely loaded, we actually needed to enable it in order to install Roundcube with the MySQL/PDO option in the first place. It seems like the live server's PDO class needs to be updated, I'm guessing? I do not have direct control over the live server, but I can give instructions to the guy who does. Can anyone help me figure out what must be done?

Here are the stats:

Here are links to pasties of the php.ini file (content was too large go to add to this post): Part 1, Part 2

What's the minimum we need to do to get these missing properties into the live server's PDO library? Actually, what is even going on here, why are they so different?

  • On linux host, are you using libmysqlclient or mysqlnd? Commented Dec 24, 2013 at 12:24
  • @WesleyMurch Look at phpinfo() Commented Dec 26, 2013 at 20:29
  • @Greshnik I don't see either one: umpire.biz/_test/phpinfo.php Commented Dec 27, 2013 at 0:51
  • @WesleyMurch As I expected, this is mysqlnd related. See my answer below. Hope this helps! Commented Dec 27, 2013 at 1:09

So you just forced me to rebuild my PHP without mysqlnd (like your build, using only libmysql backend) to check my theory. Fortunately I have a Gentoo installation to do it quick!

As I expected, without mysqlnd, there are NO ANY PDO::MYSQL_* constants in PDO class at all. So to get them in place, you should use mysqlnd: either recompile PHP, or possibly get an pdo_mysqlnd.so (or php_mysql.so built against mysqlnd) extension and load it.

Windows PHP binary seems coming compiled with mysqlnd.

By the way, mysqlnd is default backend as of PHP 5.4.0.

  • I think you are right, just emailed our server guy and should have results soon. Commented Dec 27, 2013 at 18:55
  • Still haven't heard the results (we may just upgrade PHP) but the bounty is running out, thanks very much for your help. Commented Dec 30, 2013 at 5:27

The missing constant gets declared in ext/pdo_mysql/pdo_mysql.c, which depending on your system is available in either of the following modules:

  • pdo_mysqlnd.so
  • pdo_mysql.so

When you run php -m you will be able to see if any of those modules is actually loaded; you would be looking for the pdo_mysql module.

To compile the module against mysqlnd into the PHP binary itself:

./config.nice --enable-mysqlnd --with-pdo-mysql=mysqlnd make && make install

  • Yep actually we had to enable this to get PDO working in the first place on the UNIX server, but that's when we came upon the error. So the file's loaded it seems. Is there some way to check if the php_pdo_mysql.dll is up to date or something? Commented Dec 20, 2013 at 20:55
  • I'm sure that it's loaded, as I had to uncomment ;extension=php_pdo_mysql.dll in php.ini just to get PDO working at all. Or am I misunderstanding something? Just to be clear, it's on the UNIX server that I'm dealing with this issue, my local Windows install is fine. Commented Dec 21, 2013 at 12:54
  • Added a bounty and the live php.ini file if you can help me further, thanks Jack. Commented Dec 23, 2013 at 20:33
